How would aristotle have ordered these on his ladder of nature?

The options are not given in the question, I found the exercise and here are the options:

Frogs, Rocks, Humans and Flies.

Aristotle’s main work on this was classification of animals, the Scala Naturae or Ladder of Nature, which was not evolutionary in its structure. It included everything from God to minerals etc. The mentioned objects will be in the following order according to the ladder of Nature:

Lowest on the ladder: Rocks,

Lower: Frogs Lower still: Flies Highest on the ladder: Humans
